Lowest-Floor Boss

April had entered its third week since Allen and the others first ventured into a dungeon.

During that time, they made an important discovery. When Allen first cleared the first floor of a dungeon and proceeded to the second, he left behind a summoned beast and some firewood.

He had done so because the Dungeon Integrated Operation Management System, a cube-shaped object, had told them something when they first entered. He hadn’t paid much attention at the time, but he decided to test a possibility that had occurred to him.

'The dimension you are sent to differs depending on your adventurer party and the room number you enter. No other adventurers will come, so no help will arrive. Please make thorough preparations.'

At first, he’d understood that being in a different dimension meant other adventurers couldn’t enter. He’d been thrilled to learn he could summon as many beasts as he liked without anyone seeing, but as they made their way through the dungeon, he realized there might be another possibility.

That possibility had occurred to him because Room 205 was so small. It could barely fit twenty people, and there was no way it could hold fifty. But the Real Estate Guild employee had said that parties of fifty went into dungeons.

Perhaps the rooms used to enter B- and A-rank dungeons were larger.

According to the Dungeon Integrated Operation Management System, the dungeon you entered didn’t differ based on the individual adventurer. Rather, the dungeon’s dimension differed according to the room and the adventurer party.

Allen wondered if parties of around fifty split up to enter multiple rooms, then joined up again in a dungeon in the same dimension. If so, they might be able to enter the same dungeon again. Being able to return to the same dungeon was important.

To test that idea, Allen left an easy-to-spot marker. When they reentered the dungeon that same day, they were able to return to the second floor of the C-rank dungeon where the firewood and summoned beast were waiting...
